Local network: You will see how to connect the ESP32 to a WIFI network and how to make the board communicate with other boards or an Android device. I worked with the predecessor, the ESP8266 and I think that the ESP32 is way easier to use and the SDK (called ESP-IDF) is much more powerful compared with the ESP8266. Press a button on the board to take three measurements of the wireless network signal strength and post the average result to a ThingSpeak channel. Connecting to a WiFi  Our sketches do not compile successfully with ESP32 Board libraries higher than 1. The procedure shown here is based on the guide provided for the ESP8266, on the MicroPython documentation website, which I encourage you to read. Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Now if we can transfer the data from one network to the other network [Internet] the ESP32 will achieve the status of a Router! Therefore, we have to achieve those feats now. connect() - connects to the Internet, all network functions works the same as with WiFi Internet connection network.
